Patents by Inventor Michael Robert Wertheimer

Michael Robert Wertheimer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9029296
    Abstract: There is described herein a superconducting segment and method of making same comprising one or several layers with very high electrical resistivity, acting as a current flow diverter when the current transfers from the superconductor to the stabilizer. The purpose of this current flow diverter is: i) to increase the contact resistance between the superconductor and the stabilizer, by reducing the contact area, and ii) to force the current to flow along a specific path, so as to increase momentarily the current density in a specific portion of the stabilizer. The consequence of i) and ii) is that heat generated at the extremities of the normal zone is increased and spread over a longer length along the superconducting segment, which increases the NZPV and thus, the uniformity of the quench.
    Type: Grant

  • Patent number: 7298072
    Abstract: An improved transparent support substrate in an organic light emitting diode (OLED) device comprises an organic polymer support film and a composite layer on the support film which is disposed intermediate the support film and the diodes of the OLED; the composite layer has first and second discrete coating layers bonded together in opposed facing relationship; the layers are of material impermeable to oxygen and water vapor but contain inadvertent discontinuities which result in discontinuity-controlled permeation of oxygen and water vapor.

  • Patent number: 7074501
    Abstract: A multilayer structure has barrier properties for gases and vapors, for example oxygen and water vapor; the structure comprises: an organic substrate layer, and a multilayer permeation barrier thereon; the barrier comprises: a) a first inorganic coating contacting a surface of the substrate layer, and b) a first organic coating contacting a surface of the inorganic coating; the structure may be employed in a variety of articles where barrier properties are important especially in electronic articles such as organic light emitting diode devices where superior barrier characteristics over the life of the device are required.
